4 of the 12 Jeeps I have had in the last 20 years have had all kinds of monkey business alarm crap on them. I may have some pictures of some of the alarm stuff I pulled from the latest TJ I have. It was crazy the mess and butt splices, those fold over and squeeze with pliers taps, blade connectors etc. All poor quality, miles of extra wires just zip tied and wadded on top of factory stuff...... Bizarre that an employer will pay a "installer" to hack up a customers vehicle to put some crappy alarm in it. These same installers usually put your car stereo in at auto accessory shops too so you can guess how well that job goes.
A favorite cut and splice point is always the main ignition start lead from the ignition key as a "starter disable" for the alarm to trigger some generic relay to allow your vehicle a start. They also like to tap into the lights so everything can flash or blink.
I wonder how many of these alarms will be installed on a Tesla or some other late vehicle?
Fortunately, these guys and alarms are going by the way of the Do-Do bird....... Eventual extinction.
Locking your soft-top Jeep is asking for your top to get knifed even though the thief or intruder could simply slide the zipper with their fingers.......
I've found the best deterrent is a fake alarm that's super simple to install in a couple places:
1. A blinky high intensity LED in the dash prominently placed where at night or in a parking structure you can see it flashing so it "looks" the part.
2. Activating the anti-theft lamp hole in the instrument cluster with another S-L-O-W blinking LED so when those would-be thieves look in the window at the dash they see it blinking there and think, hmmm.... this may take more time than I'm willing to spend disabling for the quick smash-&-grab. Basically buying you time that they may get noticed or caught peeping around.
That's it....
If someone wants your unsecured property badly enough, they will roll up with a trailer dolly, flatbed or box truck and it will disappear without a trace ALARM OR NO ALARM unless you have security servelance watching over, the Jeep is pinned in where they can't get to it easy enough or it would risk them getting caught and a good guard dog is on duty...
Remember the yard signs posted No Trespassing: (Never-mind the dog...... Beware of Owner!
) ?
Too bad stealing a man's car wasn't tanamount to stealing his horse back in the day with a similar punishment.
